TO_CHAR function not available in H2 database

问题

I am using H2 database for integration test. The code is quiet old and is using JDBC queries instead.

While running tests i am getting the error below

org.h2.jdbc.JdbcSQLException: Function "TO_CHAR" not found; SQL statement:

I can see that H2 does not implecitely supports TO_CHAR function. Is there any way to add a custom methor or should i think about moving to HSQL DB or any other database for testing purpose.

回答1:

Use the newer version 1.3.175. Since 2014-01-18 available with a TO_CHAR function.

回答2:

You could try HSQLDB of course. I think it does support TO_CHAR.

Or you could write a user defined function in H2.
